BENGALURU (Reuters) - Gold edged lower on Wednesday, although still holding near its highest in seven months, supported by a weaker dollar ahead of key political and economic events that are expected to stoke bullion's safe-haven appeal.
A national election in the UK, a European Central Bank policy meeting and former U.S. Federal Bureau of Investigation (FBI) director James Comey's Senate testimony are all occurring on Thursday.
The events have the potential to boost the appeal of bullion, which is often used as an investment option during times of political and financial uncertainty.
A combination of geopolitical concerns, including the UK elections and a wilting U.S. dollar as Wall Street loses faith on U.S. President Donald Trump delivering on his campaign promises, have kept gold's bullish streak going, said Jeffrey Halley, a senior market analyst at OANDA.
"With the degree of uncertainty around as we head into the latter half of the week, there would appear to be no reason for gold's march higher to peter out," Halley said.

A U.S. interest rate hike in mid-June should yield a more expensive greenback and pull gold prices lower, Gan said.
